chines; and I do declare the following. to be the plane designated by the line 3-3 of Fig."

a full, clear, and exact description of the invention, such as will enable o thers skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide *animproved type of ore washing machine in which the water 1s moved through the ore supporting screens by pulsating one side of the water tank, said side being formed of flexible metal.

With the foregoing general object in view, the invention resides in certain novel features of construction and in unique combinationsof parts to be hereinafter fully described and claimed, the descriptive matter being supplemented bythe accompanying drawings which constitute a part of this application and in which:

Figure 1 is a top plan view of .the improved machine;

Fig. 2 is a vertical longitudinal section on the plane of the line 2 2 of Fig. 1;

Fig. 3'is a vertical'tran'sverse section on I 2; and,

Fig. 4 is a horizontal section on the plane designated by the 1in@ 4-4 of Fig. 2.

In the drawings above briefly described the numeral 1 designates an elongated rectangular water tank whose rear side 2 is formed of a iiexible sheet of metal, said tank being divided into a pair of compartments C and C by al transverse partition 3 while the upper ends of both of these compartments are divided by longitudinal partitions 4. The four edges of .the rear wall 2 are' preferably bent forwardly to forni flanges 5 secured by Iiails, screws or the like 6 to the ends and bottom of the tank'and Ato bars 7 extending between, the upper; end of the par-- tition 3 and the ends of the tank.v Along its vertical center screws or the like 8 secure the wall 2 to the rear edge of the partition 3.

In rear of the partitions 4 closures 9 are provided for the compartments C and C v,said closures having manholesl closed by doors 10 which are equipped with suitable 'the single pipe 17 supplies Water to both compartments C and C', it being obvious that this water will overflow through the notch 13.

A longitudinal shaft 18 is disposed in rear of the tank l vand is rotatably supported upon suitable bracket arms 19 secured to the ends of said tank, said shaft being provided on one end with a crank or the like 2O by means of which it may be driven. It will be ,understood that if the machine is to be operated by any other means than hand power the crank 20 may be eliminated in lfavor of a pulley, sprocket or the like. rlhe shaft 18 is provided with a pair of diametrically opposed cranks 21 'connected by links 22 with the opposite halves of the i flexible wall 2 so that as the shaft is rotated said wall will be pulsated to move the water upwardly and downwardly through the Ascreens 12 to wash the ore fed to said screens in any suitable manner.

It is to beobserved that when one-half of the wall 2 is flexed outwardly the other half thereof is similarly moved inwardly. This is highly important since it not only prevents excessive vibration of the machine but any tendency on the part of the outwardly moving half of the wall 2 toloosen the fasteners 8 is resisted by the other half which is simultaneously shifted inwardly.

From the foregoing taken in connection with the accompanying drawings the construction and manner of operation of the improved machine will be understood to thoseskilled in the art and it will be observed that although the apparatus is lof comparatively simple nature it is highly etticient and durable. For these reasons the construction shown constitutes the preferred form ofthe machine but it is to be-understood that within the scope of the invenpart by driven lfasteners, means operativelyconnected with one half of said sheet for alternately pushing it forwardly and pulling it rearwardly, and simllar means operatlvely connected to the other half of said sheet, one

of said means being opposed to the other, wherebyv any tendency of one half of the sheet to pull upon and withdraw said driven fasteners, is resistedby the other oppositely moving half of said sheet.

2. In an ore Washing machine, the combination of a rectangular water tank divided by a transverse partition into a pair of compartments, the entire rear Wall of said tank being formed of a single iexible sheet of metal having attaching anges on its edges secured to iixed parts of 4the tank, driven fasteners eXtendin through the vertical center of said sheet o metal into the rear edge of said partition, means operatively connected with one half of said sheet for alternately pushing it forwardly and pulling it rearwardly, and similar means operatively connected to the other half of said sheet, one of said means being opposed to the other, whereby any tendency of one half of the sheet to pull upon and Withdraw said driven fasteners, is vresisted by the. other oppositely moving half of said sheet.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
